- distinguish log.Error and log.Errorf functions
- Initialize structs with field names
- A bit of unreachable code (defers)

and other logging switches. I kept the u.PErr and u.POut in cli

- use automatic type conversions to .String()
  (Peer.String() prints nicely, and avoids calling b58 encoding
  until needed)
